That's an EXCELLENT idea! You could also ask her for some websites they can do on their own, or at least a copy of the summer reading lists.The work that is being sent is maybe 15 minutes for a whole week. I am not too happy about it. I am honestly thinking about asking my friend that works for the high school to create teaching lessons for my kids because I know she will in a heartbeat.
DD's English teacher assigned his Honors class a book to read then goes online with all the kids to discuss it. Most of the titles HS kids read nowadays are either classically relevant (Catcher in the Rye was DD's most recent book) or new ones that we never read as kids. Her Honors book is The Road, which we are both reading, now.
You can do the same thing at home. If you get the teaching guide that goes along with the text, you can read along with your kids and do a family discussion. Amazon sells teaching guides for many books, and they're generally very reasonably priced. Your local community college should have some, as well. The on-campus book stores are still closed around here, but we can still order online.
And don't discount your local library! There's been a big push lately to make more books available online - and most of them have already published their summer reading lists!
You can do this ... and you may actually find that you all enjoy it. My kids used to argue over who got to pick the next book. Now grown, or nearly so, they actually read on their own. Mission Accomplished!
